            <br />

            <h4>一：设置编辑器验证规则</h4>
<pre class="code"><span style="color: blue">&lt;</span><span style="color: maroon">div </span><span style="color: red">field</span><span style="color: blue">="loginname" </span><span style="color: red">width</span><span style="color: blue">="120" </span><span style="color: red">headerAlign</span><span style="color: blue">="center" </span><span style="color: red">allowSort</span><span style="color: blue">="true"&gt;</span>员工帐号
    <span style="color: blue">&lt;</span><span style="color: maroon">input </span><span style="color: red">property</span><span style="color: blue">="editor" </span><span style="color: red">class</span><span style="color: blue">="mini-textbox" </span><span style="color: red">style</span><span style="color: blue">="</span><span style="color: red">width</span><span style="color: blue">:100%;" </span><span style="color: red">required</span><span style="color: blue">="true" </span><span style="color: red">vtype</span><span style="color: blue">="email"  /&gt;
&lt;/</span><span style="color: maroon">div</span><span style="color: blue">&gt;       
</span></pre>
            <p>使用编辑器的vtype和onvalidation事件，可以实现编辑器验证规则。详细可以查看：<a href="validator.html">数据验证</a>。</p>


            <h4>二：监听处理cellcommitedit事件</h4>
<pre class="code"><span style="color:#006400">//提交单元格编辑数据前激发
</span><span style="color:blue">function </span>onCellCommitEdit(e) {
    <span style="color:blue">var </span>editor = e.editor;
    editor.validate();
    <span style="color:blue">if </span>(editor.isValid() == <span style="color:blue">false</span>) {
        alert(editor.getErrorText());
        e.cancel = <span style="color:blue">true</span>;
    }
}
grid.on(<span style="color:maroon">"cellcommitedit"</span>, onCellCommitEdit);
</pre>
            <p>Grid的cellcommitedit事件，在编辑值提交前激发。此时，可以调用编辑器的验证方法validate，判断输入的内容是否符合验证规则。</p>
